DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

FIG. 1 shows a perspective view, taken generally above a first embodiment of a portable exercise apparatus 10. The apparatus 10 has a base member 12. The base member 12 has a body 14 with an upper surface 16 and a lower surface (illustrated in FIG. 3 only as lower surface 18). The body 14 in the illustrated preferred embodiment of the apparatus 10 is in the form of a disc. However, it will be appreciated that in the broadest concept of the present invention, the body 14 may take the form of polygon, oval, irregularly curved shape and may have one or more voids (not illustrated). The body 14 is preferably formed by sewing or otherwise affixing a lightweight, durable material such as nylon or tear-resistant textile constituting the upper surface 16 and lower surface 18. Preferably, a pliant, compressible material 17 such as foam, rubber, cotton, fabric, or other natural or synthetic material is distributed and retained between the affixed upper surface 16 and lower surface 18.

In the illustrated preferred embodiment, the body 14 of the base member 12 is pliant or otherwise capable of being configured in a collapsed position as illustrated in FIG. 2. The body 14 may be rolled or folded in order to decrease the footprint of the portable exercise apparatus 10, thus rendering it amenable to storage and transportation. It is preferred that when the body 14 is in the collapsed configuration, it may be easily carried in a handbag, purse, backpack, over the shoulder of the user, or under the arm of the user of the apparatus 10.

As can be seen in FIG. 1, the body 14 preferably has a deployed configuration when the apparatus 10 is ready for use. In the deployed configuration, the body 14 is generally planar for resting on a seat or the ground, as will be discussed in detail hereinafter.

In the illustrated preferred embodiment shown in FIGS. 1 and 2, the body 14 has a pair of handle members 19 for being gripped by a user of the apparatus 10, during some modes of operation of the apparatus 10. The handle members 19 enable the user of the apparatus 10 to increase the normal force exerted upon the body 14 when the user is seated upon the body 14. The midpoints of the handle members 19 may be thought to define a plane, running generally normal to the upper surface 16 of the apparatus 10, bisecting the body 14 into a first or forward half and a second or rearward half. When a user of the apparatus 10 is seated upon the base member 12, the forward half is proximal the legs of the user, while the rearward half is proximal the posterior of the user. Preferably, the handle members 19 are each a strip of material that is the same material as the upper and lower surfaces 16,18 of the body 14, with the handle members 19 being sewn in between the upper and lower surfaces 16, 18. The handle members 19 may be constructed from any material, depending on the intended application of the apparatus 10.

As shown in FIG. 1, the body 14 further has one or more attachment points 20. In the illustrated preferred embodiment, the attachment points 20 are D-ring type connectors retained by integral loops extending outwardly from the perimeter of the body 14. The attachment points 20 of the base member 12 serve as anchor points for one or more elongate members 30, the elongate members 30 being generally elastic and which will be discussed in detail hereinafter.

In the illustrated preferred embodiment of the apparatus 10, the body 14 has six attachment points 20 for use with the elongate members 30 (FIG. 1). Two of the attachment points 20 are located on forward half of the body 14, as defined by the aforementioned plane running through the midpoints of the handle members 19. Two of the attachment points 20 are located on rearward half of the body 14, as defined by the aforementioned plane running through the midpoints of the handle members 19. Preferably, the attachment points 20 located on the forward and rearward halves of the body 14 are each separated by 90 degrees. The preferred embodiment of the body 14 further has two opposing, lateral attachment points 22 positioned between the attachment points 20 on the forward and rearward halves of the body 14. It has been found that the location of the forward, rearward, and lateral attachment points 20, 22 provides a versatile set of anchor positions for the elongate members 30 for a variety exercises performed while the user is seated, standing, or lying.

It will be appreciated that in the broadest concept of the present invention, the body 14 need only have one attachment point 20, and such attachment point 20 may be located anywhere on the body 14. Furthermore, the attachment point 20 need not be in the form of a D-ring type connector, and may be any type of conventional permanent or releasable connection.

As can be seen in FIG. 1, the body 14 preferably has one or more reinforcing members 32 extending from one of the attachment points 20 or lateral attachment points 22 to another of the attachment points 20 or lateral attachment points 22, respectively, through a geometric center of either the upper surface 16 or the lower surface 18. The reinforcing members 32 serve to distribute the tensile forces applied by the elongate members 30 to the attachment points 20 or lateral attachment points 22, when the user is forcing the elongate members 30. Furthermore, when the body 14 is of the collapsible type, the role of the reinforcing members 32 is further enhanced because only the surfaces 16, 18 are load bearing. Thus, when the body 14 is of the collapsible type, the reinforcing members serve to reduce the possibility of material failure of the surfaces 16, 18. The reinforcing members 32 are preferably made from a durable woven material, such as nylon straps.

Referring to the illustrated preferred embodiment of the apparatus 10 in FIGS. 1 and 2, each of the one or more elongate members 30 has a proximal end 34 and a distal end 36. The proximal end 34 attaches to an attachment point 20 or a lateral attachment point 22 to anchor the elongate member 30 to the body 14. The proximal end 34 may be tied directly to or integral with the attachment point 20 or lateral attachment point 22, or the proximal end 34 may have a releasable type connection such as clip or hook. The distal end 36 of the elongate member 30 may be gripped directly or tied to an appendage of the user, or the distal end 36 may have a releasable type connection such as clip or hook operatively attached to a grippable member 38. The grippable member 38 may be in the form of a foot stirrup, loop, handle, appendage wrap, or other suitable attachment for connection to the user's body. As can be seen in FIG. 3, the grippable member 38 has the form of a handle. As can be seen in FIG. 5, the grippable member 38 has the form of a foot wrap. The elongate members 30 are resistive elastic members that are suited for providing repeatable, elastic resistance against the exertions of the user of the apparatus 10. Typical materials utilized for the elongate members 30 are real and synthetic rubbers, or other elastomers that may be tuned to provide a specific linear or non-linear force to resist movement of the user.

Referring to FIG. 3, the lower surface 18 of the body 14 preferably has a one or more loop members 40 extending outwardly from the body lower surface 18. The loop members 40 are for receiving, and thus serving as anchor points for, one or more auxiliary elastic members 41, such as a band or a strap, provided by the user. The attachment of the elastic member 41 through one or more of the loop members 40 increases the versatility of the possible exercises enabled by the apparatus 10, as will be discussed in detail hereinafter. The loop members 40 are preferably made of the same material as the reinforcing members 32.

Still referring to FIG. 3, the lower surface 18 of the body 14 also preferably has a one or more routing members 42 extending outwardly from the body lower surface 18 proximal to one or more attachment points 20 and/or lateral attachment points 22. The routing members 42 are for receiving a portion of the elongate members 30 in order to shorten to adjust the length of the elongate members 30. The shortening of the elongate members 30 by threading through one or more of the routing members 42 adjusts the elongate members 30 to the needs of each unique user of the apparatus 10. The routing members 42 are preferably made of the same material as the reinforcing members 32.

Two modes of use are illustrated in FIG. 4, where the user is seated upon the apparatus 10. The first mode of use shows the user seated upon the upper surface 16 of the body 14 and the proximal end 34 of the elongate member 30 is anchored to a lateral attachment point 22. The user is illustrated holding the grippable member 38, which is attached to the distal end 36 of the elongate member 30. The user is illustrated performing a lateral extension of the user's arm against the resistance of the elongate member 30 in order to strengthen the user's arm, shoulder, and back. It will be appreciated, that other exercises such as chest presses, military presses, forward and rearward arm raises, cross arm raises, etc. may be performed in this mode, wherein the elongate member 30 may be attached to any attachment point 20.

The second mode illustrated in FIG. 4 shows the user seated upon the upper surface 16 of the body 14 and the proximal end 34 of a second elongate member 30 anchored to a forward attachment point 20. The user is illustrated with the user's foot wrapped by another grippable member 38, which is attached to the distal end 36 of the second elongate member 30. The user is illustrated performing a forward leg extension against the resistance of the second elongate member 30 in order to strengthen the user's leg, knee, and torso. It will be appreciated, that other exercises such as lateral leg extensions, rearward leg extensions, and cross leg raises, etc. may be performed in this mode, wherein the second elongate member 30 may be attached to any attachment point 20 or lateral attachment point 22.

Another mode of use is illustrated in FIG. 5, where the user is seated and grasping the apparatus 10. This mode of use shows the user seated and grasping the handle members 19 of the body 14. The proximal ends 34 of two elongate members 30 are anchored symmetrically to two attachment points 20. The distal ends 36 of two elongate members 30 are attached to two grippable members 38, which are wrapped about the user's feet. The user is illustrated performing a lateral pulling exercise of the user's arm against the resistance of the two elongate members 30 in order to strengthen the user's biceps, shoulders, and back. It will be appreciated, that other exercises such as leg extensions, arm raises, etc. may be performed in this mode, wherein the elongate member 30 may be attached to any attachment point 20 or lateral attachment point 22.

Another mode of use is illustrated in FIG. 6, where the user is supine on the apparatus 10. This mode of use shows the user's backside against the apparatus 10 and the user exerting forces against four elongate members 30 (two of the elongate members are not visible from this perspective). The proximal ends 34 of all four elongate members 30 are anchored symmetrically to four attachment points 20. The distal ends 36 of two elongate members 30 are attached to two grippable members 38, which are wrapped about the user's feet. The distal ends 36 of the other two elongate members 30 are attached to two grippable members 38, which are gripped by the user's hands. The user is illustrated performing an abdominal exercise as the user rotates his or her torso away from the body 14 and against the resistance of the four elongate members 30. It will be appreciated, that other exercises such as leg extensions, arm raises, etc. may be performed in this mode, wherein the elongate members 30 may be attached to any attachment point 20 or lateral attachment point 22.

It will be appreciated that a variety of exercises are possible with the apparatus 10 and the exercises illustrated in the figures are to be interpreted as exemplary only.
